Scaratmis COLEOPTERA: 27 



Of this genus there are three fedlions or 

 families, diftinguifhed from one another as 

 follows : 



1. Thofe in which the thorax is armed 

 with horns. 



2. Thofe which have that part fimplc 

 or unarmed, but which have horns on their 

 beads. 



3. Thofe in which the head and thorax 

 are both fimple or without horns. 



Some of the infefts belonging to each of thefe 

 families, are fcutellati^ or furnifhed with the 

 part called the ejcutcheon^ and others belonging 

 likewife to each of them, are excutellati^ or want 

 that part. This circumftance has induced Schsef- 

 fer and Geoffroy to divide the Scarabsei into two 

 genera, the one called Scarabaus^ containing 

 fuch as have the efcutcheon, the other 

 termed Copris, compofed of thofe which 

 want it. 



The Scarahrti in each of thefe two laft mention- 

 ed anthors, are divided into different families or 

 fedtions, from the number of the plates or lami- 

 na^ of which the club that terminates the an- 

 tennae is compofed.
